How Do Angle Rolls Operate?

Angle rolls can bend metal into many different shapes. Angle rolls are often controlled by a computer, especially in manufacturing environments where precision is key. Angle rolls consist of three main components:

1) Rolling Mill:

Angle rolls are manufactured in rolling mills. These massive machines can roll metal into shapes that are impossible to make by hand. It consists of a single vertical roller that is connected to a motor, allowing it to roll the metal into a variety of different shapes.

2) Angle Roll Stocks (Sheet Metal, Square Stock, Angle, or Flat Bar):

Angle rolls can be used to make a variety of shapes out of metal, not just angle irons. It can turn sheet metal into perfect squares or steel bars into round tubing without any additional equipment. Angle roll stocks are often custom-built and designed specifically for the type of product they will produce. Angle iron is a commonly used abbreviation for angle roll stock.

3) Angle Rolls Tooling (Roll Forming Tools):

Angle roll tooling is used to shape angle roll stock into a specific size. Angle roll tooling most commonly consists of a pair of C-shaped dies with a movable plunger. Angle rolls include a die pocket that holds the angle iron stock in place, while the plunger presses it through the roll tooling.


Various types of metals:

The weight capacity of an angle roll has a significant effect on the type of metal it can process. Angle rolls are available in light-duty, medium-duty, and heavy-duty types. Angle rolls can work with metals or shapes other than angle iron. Angle rolls can process other metals as well, including aluminum and stainless steel. They are built to handle specific types of metal, so it is important to choose the right one. Metals such as stainless steel and copper alloys, which are malleable, can only be processed by some machines, whereas industrial-grade steel can be processed by others.


Distinctions in the Rolls

The machine's "rolls" are the rotating round parts that bend and shape the metal. Angle rolls can be made from different materials. Angle iron is usually made from carbon steel, which is less expensive than stainless steel and more resistant to corrosion. Angle rolls can also be constructed of ductile iron or cast iron, depending on the type of machine. Ductile-iron angle rolls are lightweight and attractive but cost significantly more than carbon-steel angle rolls. Angle rolls are also available in two types of roll bending: friction and hydraulic.

Friction Roll Angle Iron Bending machines use a pair of grooved cylinders to bend the angle iron. The grooves on the inside of the C-shaped die grip and bend angle iron stock into various shapes like angles, squares, rounds, and flats. Angle iron dies are available in many different sizes to produce angle iron stock with small or large radii, depending on application requirements.

Hydraulic Angle Iron Bending machines use hydraulic pressure to bend angle iron stock into various shapes like angles, squares, rounds, and flats. They operate much the same way as friction roll bending machines. Angle rolls can bend material from 2-1/2" x 3/8" thick up to a heavy-duty 4" x 1-3/8" thick. Angle rolls are available in different models, with each machine being designed for a specific metal size range and material thickness.



Shapes angle iron:

An angle roll machine can be used to shape metal into a specific shape for a specific application. A sheet of metal can be turned into a variety of different shapes, such as angle irons, solid squares, pipes, round tubing, and more by angle rolls.

Efficiency, comfort, and productivity:

The combination of power, maneuverability, and quick cycle time makes this an attractive choice in a wide range of applications. The powerful performance of this part-revolution press brake permits the bending of thicker material to angles from 75° to 105° in one stroke with accurate results. The shorter arc length makes it possible for parts to be loaded into the press brake from the front or back, giving the operator more flexibility.

The high degree of accuracy and repeatability:

The accuracy and repeatability of the machines are at the heart of any bend, ensuring that each time a part is created it meets customer specifications. Repeatable results are essential to a quality end product.

High-quality workmanship:

Every press brake needs a solid foundation of high-quality machinery to produce accurate parts consistently with a minimum of maintenance. Each tool in a press brake is precisely ground and leveled to make sure it meets the highest standards for accuracy throughout its entire working life.

Strongly built:

The angle roll machine is built to be extremely strong. Each tool must be precisely aligned to ensure that it can bend or straighten material as expected every time. A press brake not only has a heavy-duty base but also a solid framework to reduce vibration and provide maximum stability.


Benefits of having Angle Rolling Machine

Angle rolls have many advantages over other systems used to shape metal into angle irons, squares, rounds, flats, or any other shape. Compared with hydraulic forging presses that use dies and hammers to bend the material, angle rolls are much safer.

  1. Angle rolls do not have exposed hammers flying at high speeds, and there is no danger of the operator being injured by a die slipping or "bouncing" during the bend.
  2. All-welded angle rolls can produce parts of any length and easily change angles by simply adjusting the machine's controls.
  3. Angle roll machines operate smoothly and quietly because of their heavy, precisely balanced castings and bearings. They don't require a lubrication system or an air compressor to run.
  4. The all-welded steel construction and simple design of the angle roll machines make them highly durable.
  5. They are remarkably easy to maintain, and parts can be replaced quickly without special tools or equipment, making them ideal for high-volume production applications.
  6. The twin-cylinder power pack on our angle roll machines provides rubber pad control, which makes it possible to produce accurate, repeatable parts by simply pulling the handle.
  7. It's easier to learn to use than many other types of brakes, making it an excellent choice for entry-level operators.
